External Detector Alarm Displays

A remote indicator must be connected if the aspirating smoke detector is not directly visible
or has been mounted in false ceilings or floors. The external detector alarm display is installed
in an obvious place in halls or entrances of the building section or areas concerned.
Remote indicators can be actuated via the optional relay board. If FNS-320-TM-R variants with
fire source identification are used, the remote indicators are assigned to the various
monitoring ranges by the relay board and, in the event of a fire, identify the location of the
fire.

Pipe system components
During planning/design, a distinction is drawn between area monitoring and equipment
monitoring. For both applications, PVC pipes and halogen-free pipes can be used but the
restrictions of EN 54.20 must be observed. The pipes used for equipment monitoring should
be halogen-free.
The figure shows essential accessory components that can be selected for the application
concerned.
The pipe system must be constructed using pipes with an external diameter of 25 mm and the
associated fittings.
